Then again, to me it's... odd that to say that you can know that you won't like the changes before even seeing them. There can be great touch UI's and poor touch UI's, just as there are great and poor non-touch UI's. If somebody feels that no touch UI can be great, then I guess we can agree to disagree and leave it at that. If somebody feels that you can do both at the same time on the same device, get the best of both worlds, based on my experience I say that it isn't so... But that's a great topic for discussion, it's not a given or an absolute fact.
